Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33606440, here are decompositions:

67 + 33606373 = 33606440
73 + 33606367 = 33606440
79 + 33606361 = 33606440
97 + 33606343 = 33606440
139 + 33606301 = 33606440
157 + 33606283 = 33606440
163 + 33606277 = 33606440
193 + 33606247 = 33606440

Showing the first eight; more decompositions exist.
